The square footage of your room will dictate the correct ceiling fan blade size. For example: 

• Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

• Rooms up to 175 square feet require 42- to 48-inch fans.

• Rooms up to 350 square feet require 52- to 56-inch fans.

• Expansive spaces over 350 square feet need a fan larger than 60 inches.

It is unlikely that a ceiling fan will fall, even if it develops a wobble. During a proper installation, ceiling fans are securely bolted to a ceiling joist, and the fasteners used for mounting are generally separate from the components related to balancing. A wobble is typically caused by an imbalance, which can be annoying and may lead to other issues, but is not usually dangerous on its own.

However, if a fan is wobbling because it was not installed correctly, it could be at risk of falling. For safety, it's always a good idea to ensure all mounting screws are tight and to address any wobbling or imbalance issues promptly.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

If your ceiling fan is humming, that's usually a sign of an electrical issue. A low-pitched grinding sound could be caused by the motor or a lack of lubrication in the bearings, but a true humming sound will be caused by a failing capacitor or faulty wiring. Unless you have experience with electrical issues, you should call a pro for any ceiling humming noises.
